Holy fuck, I thought it was just me.

I think I do it more with black on white. I find it difficult to focus reading from a large bright screen.

I do find I end up not bothering to read a lot of articles I'd like to online, end up either bookmarking and ignoring, or just skimming over. Think it's because reading long articles in a particular layout is a chore. A layout browser extension might help, I should give it a try.
